How to Add an Interconnect Component

This procedure defines interconnect component as any one of the following components:

Transport adapter

Transport cable

Transport junction (switch)

This section contains the procedure about how to add transport adapters to nodes
in a running cluster.

Before You Begin

This procedure relies on the following prerequisites and assumptions:

Your cluster is operational and all nodes are powered on.

If Virtual Local Area Networks (VLANs) are configured, more than one
cluster might be impacted by removing a transport junction. Ensure that all clusters
are prepared for the removal of a transport junction. Also, record the configuration
information of the transport junction you plan to replace and configure the new transport junction accordingly.

PCI-SCI interconnect requires that you remove the interconnect component
from the cluster configuration because the SCI driver needs to be updated. If the
SCI driver is not updated, the nodes cannot use that interconnect to communicate.
Although this practice is optional for all other interconnect technology, remove the
interconnect component from the cluster configuration to prevent error messages from
appearing on your console.
